The MTF is an index that can faithfully reproduce the degree of contrast of the subject as a spatial frequency characteristic in order to know the performance of the lens. The spatial frequency represents the number of patterns contained in every 1 mm. The curve in which the horizontal axis represents the spatial frequency and the vertical axis represents the contrast value is a so-called MTF curve. An MTF measuring system that evaluates lens performance using an MTF curve is known (for example, refer to Patent Document 1). In the patent document, an MTF measurement system is disclosed in which an image of a subject image obtained by photographing a subject through a lens is calculated, and an MTF that is an index for evaluating the performance of the lens is calculated. The lens performance is evaluated based on the MTF curve represented by the mtf curve image data generated by the MTF data. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2002-350285. However, in the above-described MTF measurement system, there are the following problems to be solved. In other words, when the lens performance evaluation operation is performed, the user first refers to the subject image indicated by the subject image data acquired by capturing the subject using the MTF measurement system, and performs the positional comparison of the subject. Quasi and focus adjustment. 5 200809175 After receiving the measurement start instruction from the user, the MTF measurement system calculates the MTF based on the subject image data adjusted by the user, acquires the MTF data, and generates MTF curve image data based on the MTF data. Then the user evaluates the lens performance based on the MTF curve indicated by the generated MTF curve image data. Therefore, in order to perform the lens performance evaluation work, the above-described series of operations are required, and there is a problem that the evaluation of the lens performance cannot be performed efficiently. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to efficiently perform an evaluation and measurement operation of a lens performance. In order to solve the above-described problems, in the present invention, the subject image data obtained by capturing the subject and the MTF curve image data indicating the MTF curve generated based on the MTF data which is an index for evaluating the performance of the lens are used. The measurement result screen data indicating the subject image and the MTF curve image is generated, and the measurement result based on the generated measurement result facet data is displayed on the display unit. According to the present invention configured as described above, the measurement result indicating the subject image and the MTF curve image is immediately displayed during the lens performance evaluation and measurement operation, so that the user can grasp the MTF curve image based on the measurement result screen.疋No need to adjust the focus, adjust the focus of the subject image that does not appear with the MTF curve image as needed, and evaluate the lens performance according to the MTF graph and the desired X X. Therefore, it is possible to achieve an efficient operation of the valence remaining operation of the lens performance.

The control unit 11 that has received the subject image data temporarily stores the subject image data in the buffer 彳7. Thereafter, the photographing unit 12 continuously photographs the card 60 until a photographing end signal indicating the end of photographing is received from the control unit 彳彳. When the photographing unit 1 2 has acquired the subject image data, the MTF calculation unit 13 calculates the MTF based on the acquired subject image data and the preset measurement position data, and acquires the MTF data (step S3). At this time, the mtf calculation unit 13 calculates the five positions of the L-shaped marks printed on the card 6〇 (see FIG. 3) as five objects, and obtains one MTF: bedding, and then obtains Each Μτρ data is output to the control port Μ 1.

For example, even if the position of the card 6〇 is appropriate, the photographing unit 12 is not configured. In the case of being perpendicular to the card 6〇, the mtf curve image of the plurality of positions is also different. Therefore, the user can not only grasp whether it is necessary to adjust the focus of the central portion of the image captured by the lens 50, but also whether it is necessary to adjust it. The focus of the peripheral portion can further finely adjust the focus of the subject image displayed together with the MTF curve image as needed.
